How to Calculate Remarketing Audience Reach Time
To run remarketing ads, you must first fill a platform's minimum audience size (Google 100, Facebook 1,000, etc.). This tool uses Daily New Adds = Daily Visitors × Opt-in Rate and Days to Reach = Target Audience ÷ Daily New Adds.
Your opt-in rate is the share of visitors your pixel actually adds to the list, which varies from 60-90% depending on tracking blockers and cookie consent settings.
If reaching the audience takes too long, run a traffic-driving campaign alongside it, or start remarketing on a platform with a lower minimum audience requirement, such as Google Ads.

Check your audience settings in Google Analytics or your ad platform to see what share of pixel-tracked visitors get added to the list. It's typically 60-90% of visitors.
Run a traffic campaign alongside it to boost visitors, or start remarketing on a platform with a lower minimum audience requirement first.
